Serial No. tenait@ i This invention relates to paper boxes, and has for its primary object to provide a box formed from a single sheet of cardboard or like material embodying complementary in- '5 tegrally connected telescoping cover and body sections, and having certain novel features of construction whereb a large number of the boxes in a folded or knocked down condition may be very compactly arranged for storage lo purposes but which enables the marginal walls of the complementary box sections to be easily and quickly arranged and strongly braced in their erected positions.

llt is a further very .important object of l my invention to provide relatively oldable parts between the marginal walls of the body and cover sections at each side of the box formed and related to each other in such manner as will result in the automatic folding of said parts as the cover section is telescoped upon the body section of the box and `which operate to prevent abutting ed e con tact between the marginal walls of t e two box sections.

ltis a further general object of the invention to provide a one-piece paper box of the above type, 'which may be very cheaply produced, is strong and durable in its construction and may be employed as a container or package for various kinds of commodities or merchandise.

With the above and other objects in view, the invention consists in the improved folding box and in the form, construction and relative arrangement of its several parts, as will be hereinafter more fully described, illustrated in the accompanying drawings, and subsequently incorporated in the subjoined claims. l

Thiscardboard sheet is of course, of the dimensions requiredf to produce a box of predetermined capacity, and is cut or'stamped out by means of suitable dies to provide the blank as shown in Fig. 1 of the drawings. This cardboard blank generally designated by the numeral 5` 90 is creased or scored along the lines 6 and 7 to provide bottom and top walls 8 and 9 of thebody and cover sections respectively, of the box and the foldable marginal walls 10 and 11 extending along each ofthe oppositesi'de 95 edges of the body and the cover sections of the box and the marginal walls 12 and 13 respectively, which extend between the outer ends of the respective side walls 10 and 11 v and are separated therefrom by the cuts 14,

said cuts at their inner ends being extended for a short distance in an outward direction along an oblique line into the ends of the foldable walls 10 and 11, as indicated at 14, said end portion and each of said walls being further oblquely creased from the cuts or incisions 14" to the outer longitudinal edges of said walls as shown at 15. It will also be noted that the fold lines or creases 6 at the juncture between the walls 8 and 9 with the marginal walls 12 and 13 are extended transversely across the foldable marginal walls 10 and 11 as at 6. The other spaced creases or fold lines 6 provide the rear or back marginal wall 12 integrally connecting the walls 8 and 9 with each other and are also extended transversely across the side marginal walls 10 and 11 as at 6a.

The outer longitudinal edges of the marginal walls 10 and 11 at each side of the box are obliquely and convergently inclined towards each other from points spaced laterally from the fold lines 6, as shown at 16 to the opposite sides. of a notch or recess 17 in the cardboard material between the fold lines 6a. The base ed e of this notch is 0bliquely inclined as at 17', and from the opposite ends thereof to the juncture of the fold lines 6a with the fold lines 6 extending at right angles thereto, the material is scored or creased as at 18, and at the inner-ends of these creases and extending in line therewith, I preferably provide the incisions or cuts shown at 19 so as to facilitate the easy rela.- tive folding movement of the parts 20, 21 and 22. It will be noted that due to the form or shape of the notch or recess 17 the outer ends of the scores 18 are not in alignment, and the said scores extend at relatively different angles in relation to the` spaced scores 6a. Thus, the part 21 is of somewhat greater area than the part 20, while the part 22 intermediate of the arts 20 and 21 is of the greatest area and ingedly connects said parts with each other and with the back marginal wall-12 with which part 22 is connected along the score or fold line 7 a.

Each of the marginal walls 12 and 13 has a reinforcing section 23 and 24 respectively, connected therewith along the score line 25 and the outer longitudinal edge of the section 24 is centrally notched as at 26 to provide a convenient means for visually differ-v entiating between the body and cover secor secured to the marginal walls 12 and 13 by means of suitable metallic fastening devices indicated at 27. In this condition, a large number of the collapsed boxes may be arranged in superimposed relation upon each other and. compactly bound together and stored in a relatively small space.

Whenthe box or container is to be used, it is only necessary to raise or lift the marginal walls 10, 11, 12 and 13 to upright or erect positions at right angles to the plane of the walls 8 and 9 respectively. It will be noted that the fastening elements 27 are` so located that the end portions of the parts 23 and 24 are capable of flexing sufciently'so that as the end-portions of the walls 10 and 11 between the fold lines 6 and 15 are moved to erect posit-ions parallel with the planes of the marginal walls 12 and 13, they will ride under the downwardly extending reinforcing parts 23 and 24. It is understood of course, that the extremities of the walls 10 and 11, beyond the score lines 15, are permanently secured to the inner faces of the walls 12 and 13 by means of a suitable adhesive. If desired, the fastener 27 may also extend through these fixed end portions of the box walls 10 and 11. The box parts thus disposed in set up position, are clearly illustrated in Fig. 3 of the drawings.

The merchandise is placed within the body section of the box upon the wall 8 thereof, and the cover section of the box is then lifted or moved upwardly. The cover section first hingedly moves with respect to the connecting marginal walls 16 as indicated in Fig. 5 of the drawings, in which said cover section vis showndisposed at an angle of substantially 30 with respect to the outer wall 8 and the rear or back Wall 16. It will be observed upon reference to Fig. 4, that owing to the angles of the score lines 18 and the form of the recess 17, in this first movement of the cover section, the part 21 is angularly moved with respect to the part 22 and folded in an outward direction while the part 22, together with the part 20 are simultaneously drawn inwardly from the plane of the end edge of the back wall 16. In Fig. 7, the top wall 9 of the cover section is shown raised to a position of substantially 90 with respect to the bottom wal18, and it will be observed that the relative folding of the parts 20, 21 and 22 has continued, the part 21 tending to flex the end of the marginal wall 11 connected with the top wall 9 in an outward direction while the part 20 folding inwardly flexes the opposed end of the marginal wall 10 connected assente section of the box. Thus, by an entirely automatic action of the parts 20, l21 and 22, the possibility of edge to edge abutting contact between the marginal walls l0 and 1l is obviated and the box may be easily and quickly closed without requiring other manigal manipulations of individual parts of the After the box has thus been closed, the parts 20, 2l and 22 lie in closely compact relation to each other against the inner face of the rear or back wall 16 of the box. 'lhe proper relative folding movement between these parts inclosing the lbox is further assured by the provision of the slits or incisions ll at the lower ends of the oblique fold lines From the foregoing description considered in connection with the accompanying drawings, it will be seen that ll have produced a box which may be cheaply manufactured 'from paper, cardboard or other suitable material, and in which the several parts of the box remain always in permanently connected relation with each other and it is not necessary to manually manipulate interlocking tabs or extensions generally provided in boxes of this type. Also my improved box construction has an advantage, that when inthe collapsed condition seen in Fig. 2,.the parts lie perfectly Hat 'so that a large number of the collapsed'boxes can be compactly bound together for transportation or storage in a comparatively small space.

l have herein shown and described anl embodiment of the device which has been found entirely satisfactory in practical use. Nevertheless. itis to be understood that the essensect1ons.

tial features of my present improvement might also be embodied in various other alternative structural forms, and I therefore, reserve the privilege of resorting to all such legitimate c anges in the several detail parts thereof as may be fairly incorporated within the spirit and scope of the yinvention as claimed.
